Subject Current state of (dense) matrix multiplication?
Date Sun, 11 Apr 2010 20:27:26 GMT
 What's the current state of matrix-matrix multiplication in Mahout?
Are there any performance results available for large matrices?

 I have been working on a Hadoop-compatible distributed storage for
matrices. I can currently multiply two 40K x 40K dense double
precision matrices in around 1 hour using 34 systems (16GB RAM, two
Core2Quads' per node). I was wondering how this compares with Mahout.
